Abstract:

Shallow buried and unsymmetrical loaded section of tunnel have a great impact on surrounding rock stability and ground support structure, which could lead to the happening of collapses in tunnel excavation at these sections. The method of FLAC3D was employed to conduct numerical analysis of construction process on shallow buried and unsymmetrical loaded Xiejiahe section in Yanhai expressway. Thus, the deformation and stress variation condition of surrounding rock and supporting structure on Xiejiahe tunnel were gained under different excavation procedures. Based on measurement result of cross-sections from field monitoring, the mechanic characteristics of surrounding rock and supporting structure on shallow buried and unsymmetrical loaded Xiejiahe section were gained by data collection and calculation to analyze the surrounding rock stability. The conclusion could provide a reliable method for the successful construction of Xiejiahe tunnel, which could also afford technical reference for tunnel design and construction of similar geological situation.

Key words: tunnel, thallow buried and unsymmetrical loaded section, numerical simulation, surrounding rock stability, monitoring and measurement
